Precautions

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood and urine tests may be needed to check for unwanted effects.

Certain women may be at an increased risk for pregnancy while taking this medicine. If you had problems ovulating and had irregular periods in the past, this medicine may cause you to ovulate. This could increase your chance of becoming pregnant. If you are a woman of childbearing potential, you should discuss birth control options with your doctor.

Check with your doctor right away if you start having chest pain, shortness of breath, excessive swelling of the hands, wrist, ankles, or feet, or if you are rapidly gaining weight. These may be symptoms of a serious heart problem.

This medicine may cause serious allergic reactions, including anaphylaxis. Anaphylaxis requires immediate medical attention. The most serious signs of this reaction are very fast or irregular breathing, gasping for breath, wheezing, or fainting. Other signs may include changes in color of the skin of the face, very fast but irregular heartbeat or pulse, hive-like swellings on the skin, and puffiness or swellings of the eyelids or around the eyes. If these side effects occur, get emergency help at once.

If you have abdominal or stomach pain, dark urine, a loss of appetite, nausea or vomiting, unusual tiredness or weakness, or yellow eyes or skin, check with your doctor right away. These may be symptoms of a serious liver problem.

Check with your doctor right away if blurred vision, decreased vision, or any other change in vision occurs while you are taking this medicine. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).

This medicine may increase the risk for bone fractures in women. Ask your doctor about ways to keep your bones strong to help prevent fractures.

This medicine may increase your risk for bladder cancer if you take it for more than 12 months. Tell your doctor right away if you have blood in the urine, a frequent, strong, or increased urge to urinate, painful urination, or pain in the back, lower abdomen, or stomach.

This medicine may make your skin more sensitive to sunlight. Use a sunscreen when you are outdoors. Avoid sunlamps and tanning beds.

It is very important to carefully follow any instructions from your doctor about:

Other medicines—Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems.

Counseling—Other family members need to learn how to prevent side effects or help with side effects if they occur. Also, diabetic patients may need special counseling about diabetes medicine dosing changes that might occur with lifestyle changes, such as changes in exercise or diet. Counseling on contraception and pregnancy may be needed because of the problems that can occur during pregnancy in patients with diabetes.

Travel—Keep a recent prescription and your medical history with you. Be prepared for an emergency as you would normally. Make allowances for changing time zones and keep your meal times as close as possible to your usual meal times.

In case of emergency—There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies. It is a good idea to wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says you have diabetes and that lists all of your medicines.

Symptoms of fluid retention—Know what to do if you start to retain fluid. Fluid retention may worsen or lead to heart problems.

This medicine can cause hypoglycemia (low blood sugar). Low blood sugar can also occur if you delay or miss a meal or snack, exercise more than usual, drink alcohol, or cannot eat because of nausea or vomiting. The symptoms of low blood sugar must be treated before they lead to unconsciousness (passing out). Different people feel different symptoms of low blood sugar. It is important that you learn which symptoms of low blood sugar you usually have so that you can treat it quickly.

If the symptoms of low blood sugar occur, eat glucose tablets or gel, corn syrup, honey, or sugar cubes, or drink fruit juice, non-diet soft drinks, or sugar dissolved in water to relieve the symptoms. Also, check your blood for low blood sugar. Glucagon is used in emergency situations when severe symptoms such as seizures (convulsions) or unconsciousness occur. Have a glucagon kit available, along with a syringe and needle, and know how to use it. Members of your family also should know how to use it.

Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your medicine, overeat or do not follow your meal plan, have a fever or infection, or do not exercise as much as usual.
